Mets pitching prospect Jeurys Familia made his first Double-A start May 10. The right-hander picked up his first win for the Double-A Binghamton Mets on Monday night, nine starts and almost two months later.

Familia, 21, threw five shutout innings Monday night, scattering three hits, striking out six and walking three in a 7-6 win over the Portland Sea Dogs. For the season, Familia is now 1-2 with a 3.02 ERA and 1.34 WHIP with Binghamton, striking out 57 and walking 23 in 50 2/3 innings. In his past two starts – both against Trenton, the Yankees’ Double-A affiliate – Familia had double-digit strikeouts each night. He struck out 11 and walked one in 6 2/3 innings June 12, then struck out 10 and walked three in six innings June 18.

There are long-term questions about whether Familia will be able to make it as a starter, or if he’ll eventually become a late-inning reliever. But after entering the season as the No. 13 overall prospect in the Mets’ system, according to Baseball America, Familia has unquestionably moved into the Top 10, probably the top five. He’s easily among the top three pitching prospects in the system now, along with right-handers Matt Harvey and Jenrry Mejia.

Another pitcher who likely will follow the same path that first Familia then Harvey took from High-A St. Lucie to Binghamton is left-hander Darin Gorski. The 23-year-old is unquestionably old for the level, but his success there is undeniable, as well. Gorski has gone 7-0 with a 1.54 ERA, striking out 92 and walking 18 in 80 2/3 innings. Gorski was the Mets’ seventh-round pick in 2009 from Kutztown (Pa.) University.

The thing that makes Gorski’s brilliant 2011 season stand out even more is the fact that in his first two professionals seasons he did little of note. He went 3-4 with a 4.91 ERA in 13 games (11 starts) for Short-A Brooklyn after he was drafted in 2009, then followed that by going 6-8 with a 4.51 ERA in 25 games (18 starts) for Low-A Savannah last year. In both years, he also struck out less batters than innings pitched, unlike this season.

Gorski will likely get a chance to prove his worth in Double-A at some point this season. But with the B-Mets rotation currently full (with Familia, Harvey, Brandon Moore, Robert Carson and Tobi Stoner), not including starter Brad Holt who’s been moved to the bullpen after a brutal beginning to the season, Gorski may have some time left to wait.

The Mets have seen already seen the debut of their 2011 second-round pick, with left-hander Cory Mazzoni making his first appearance in pro ball with the Brooklyn Cyclones on Sunday night. Mazzoni threw a scoreless seventh inning in Brooklyn’s 3-2 loss to the Staten Island Yankees. Mazzoni gave up one hit, struck out two and walked one.

Mazzoni struck out the best prospect on Staten Island’s roster, outfielder Mason Williams, to lead off the inning. He navigated around a walk to the Yankees’ 2010 first-round pick, shortstop Cito Culver, and a single by Reymond Nunez to get out of the inning.

Because Mazzoni threw over 100 innings for N.C. State this season before the Mets drafted him, whether the Mets think he’s going to be a starter or a reliever long-term, expect Mazzoni to stick in the bullpen at least until the end of the year, in order to keep his innings down.
